Pariveda Office Manager interview questions

Resume sent in from an online posting. I was contacted via email for a phone screen. I responded the same day with my availability. I had to contact the recruiter twice via email to receive a scheduled phone screen. The phone screen consisted of a call from the local recruiter. Went over the job description, how my background and experience fit the opening, culture of the company, etc. After a 75 minute conversation, I was asked to email my availability for the next phone screen with the Regional Office Manager. Sent my availability via email the same day. No response. Sent again 2 days later without a response. Attempted a final email and received a return email - either the recruiter left the company or my email address was blocked by the recruiter. It would have been more professionally courteous to return an email stating that they were not moving forward...Strange ending to a long process.
